In many cases , a rubber belt is used, and it is almost impossible to form an endless shape from the beginning. Therefore, when a conveyor belt is mounted on a roll, both ends of a long rubber belt are joined endlessly on site. As a means for joining the conveyor belts, a tensile body is overlapped, a reinforcing cloth and a cover rubber are overlapped on both front and back surfaces, and an overlap method or a tensile body is integrated, and the reinforcing cloth and the cover rubber are attached to the front and back surfaces. A butt system that is integrated by stacking, or a tensile body is provided with a number of wedge-shaped cuts that fit in a male and female relationship with each other, and these are fitted so as to be combined, and a reinforcing cloth and cover rubber are stacked on both front and back surfaces. An integrated finger system and the like are known.

In the case of a conveyor belt having "a small number of plies (or the number of laminations)", the above-mentioned overlapping method and butting method are not suitable because the thickness of the joining portion becomes stepwise thicker than other portions, and is not suitable for finger joining. Often.

As shown in FIG. 1, the tension members 2, 2 at the opposite end portions of the conveyor belts 1, 1, each having one to two plies of tension members, are exposed to each other. As shown in FIG. 2, after forming a large number of wedge-shaped cuts 3... 3 which fit in a male and female relationship as shown in FIG. As shown in the drawing, circumferential cutouts 4 and 4 are provided, and then both cuts are fitted to each other to join them in a plane as shown in FIG. Cloth 5

In the case of a circumferential shape, a material that can be cut neatly without standing on the inner surface of the hole, such as "half moon", is used. In addition, it may be punched into a hole of an arbitrary shape by a punch or the like.
The notches 4, 4 may be formed at the same time as the wedge-shaped cuts 3,.

As a result, the effectiveness of the present invention was confirmed. In Table 1, the strength efficiency shows the tensile strength of the joint portion in% when the strength of the tensile member is 100. Further, in Table 1, Comparative Example 1 shows the results when the same belt as in Example 1 was joined without having the notch 4. In Example 2, the same belt as in Example 1 was formed with 10 wedge-shaped protrusions, and in Example 3, the same wedge-shaped protrusion as that of Example 1 was formed for a tensile body grade of 1250 KN / cm. Example 4 shows the same belt formed with the same wedge-shaped projections as Example 2, and Comparative Example corresponds to the example shown by the same numeral, and shows the result of the belt having no notch 4.

なる。In the present invention, since the notches are formed at the tips 3A and 3B of the concave and convex portions of the wedge-shaped cuts 3, when the finger joints are arranged so as to mesh with each other, the finger joints are engaged with each other by the notch amount. Allow for more room for adjustment. Therefore, new adjustment cutting is almost unnecessary.

度も優れるなどの効果も有する。As described above, according to the present invention, when the tensile member is finger-joined, notches are formed at the front and rear ends of the wedge-shaped concave and convex portions. Finger joining can be performed quickly. Further, since there is almost no gap or overlapping portion at the finger joint portion, there is an effect that the strength of the joint portion is excellent.
